Specification of Letters '.Patent.r .I Patgnteld Aug 3(6)', 1921 Application mea December 6, 191s. serial No. 265,581.

To all whom t may concern:

Be it known that I, HENRY H. HARRIS, a

citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented certain new and useful Improvements in Heating- Stoves, of which the following is a specification.

This invention relates to heating stoves,

and the primary object thereof is to conn4 struct a stove of this character which with a consumption of a minimum kamount of fuel will produce a maximum amount of heat.

, vAnother obj ect is to so construct a heating stove that whilev comparatively small and compact and occupying a small space it has a large area of heat delivering surface.

come,v excessively Aoverheated and consequently the parts exposed to vthe ire will` not burn out thereby prolonging the life of the stove and yet delivering a continuous flow of heated air to the surrounding atmosphere.v

Another object is to construct a heating stoverwith the `exits v.of the flues opening downwardly toward the iioor and directly under the footrail of the stove so that the ioor will be kept warm as well as the rail.

Wfitli the foregoing and other objects in ,.view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts andin the details of construction hereinafter described Iand claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings rFigure 1 represents a longitudinal vertical sectionlof a stove constructed in accordance with this invention, and

FigjQ is a horizontal section taken on thev line 2-2 of F ig. 1. Y

Fig. 3 is an enlarged fragmentary perspective of the heater lwith parts thereof brokenv away to show the interior construc- In the embodiment illustrated, the stove dricalin form, although not necessarily so, and which has a closed top 2 and a bottom 3 with a central opening v1 for the entrance of the cool air to the stove.

Arranged within the upper portion of casing 1 and concentric thereto is an inner drum 5, spaced laterally a suitable distance from the outer casing 1 and having a plurality ofplongitudinally disposed hot air flues 6 arranged on its inner face, said iiues being formed by corrugations as is shown clearly in Fig. 2 of the drawings for horizontal partition 6 is arranged within the drum 5 and spaced from the top thereof. The edges of this partition are secured to the upper edges of the tubes or corrugations, butdo not close the upper ends of the tubes, and is provided to prevent gases from the tire pot mixing with the air being heat Another object is to provide a stove ofthis character, the hot air flues of which arev so constructed that the stovewill never be-k ed. 4These fines 6 open at their lower ends into a space or chamber 7 surrounding and extending below the 'fire pot 7 of the stove and at their upper ends into 'a' chamber 8 formed between the top of the inner drum 5 and the partition 6', and the heated air delivered by said flues passes out of said drum through an opening 9 in its top into a chamber 10 formed at the upper end ofthe is arranged to permit air from passage 7 Ato enter passage ways 6 and operates to direct the down-flowing 'heated air through said apertures to the surrounding atmosphere. This member 13 is segmental in cross section and operates as a hood or deflector for directing the heated air delivered throughthe apertures 12 toward the floor so that the floor will be kept warm as will also the rail 13 rwhich is preferably made imperforate and will consequently prove an effective foot warmer. Y

A similarly shaped heat deflector 111 is carried by the upper end of the casing 1 and operates to deflect the air radiated from the casing downwardly into the room.

Combined bracers and spacers 15 are arranged between the inner drum 5 and the outer drum 1 so that these parts are held securely in operative position against collapse.

Air pipes 16 are arranged at diametrically,

opposite points and open at their inner ends into an annular chamber or gas ring 17 which surrounds the re pot 7, at its upper end and are designed to feed air to the fire. The upper end of the lues 16 are provided `with dampers 18, the actuating fingers20 of which are arranged on the outer face of top 2 of the drum 1 and are designed for controlling the How of air to the fire.

The iire pot 7 is shown mounted on a supporting shell, the upper portion 21 of which is slotted as at 21. The lower part of the shell is imperforate as at 22 and forms the side walls of the ash pan chamber 26, the top and bottom thereof being provided by spaced horizontal partitions 26. This chamber 26 is closed air tight, and the ylire pot V7 opens thereinto as shown clearly in Fig. 1, and rests upon the upper horizontal partition 26. This supporting shell extends to the bottom of drum 1 and thus rests thereon and is provided with openings 22 'below the bott-om of the ash panv ing the chamber 8 will pass out through the opening 9 into chamber 10 and down through chamber 11 formed between the inner and outer drums and pass out through the apertures 12 in the surrounding atmosphere.

An ash can is shown arranged below the lire pot in the air tight chamber 22, which chamber is disposed below the slotted portion of the shell, and it is equipped with a damper Ydoor (not shown) to be'used in starting the iire and lfor removing the can.

It is to be understood of course that the stove herein shown and described may be mounted on any suitable base, not shown, and that it may be ornamented in any suitable or desired manner, the door, not shown, for feeding the lire pot being formed in one side wall of the stove, preferably at the point indicated at 27 and the outlet for the products of combustion may also be connected withthe side wall or top of the stove, but as these elements form no part of the invention, it is not deemed necessary to show them. 4

From the above description it will be obvious that the heating surface ofthe stove constituting this invention has about double the area usually found in stoves of this character and that the heated air being continuously forced out into the room and cool air coming into the iiues will prevent them from burning out vand' at the same time sup guarantees a Well heated house but insures a healthful atmosphere.

It will also be obvious that by constructing the stove as above described and set forth, that a very small quantity of fuel will be necessary in order to produce a large quantity of heat and that the burning of such a small quantity of fuel will prolong the life of the stove in addition to economizing in the cost of the fuel.

The foregoing description and the drawings have reference to what may be considered the preferredor approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts,imate rials, dimensions, etc., as may prove expedient and fall within the 'scope of the claimed invention. l

Having thus fully' described lmy invention, what I claim as new and desire to secure by Letters Patent, is:
